Abstract
Poor control of U-Tube steam generator water level in nuclear power station can lead to frequent reactor shutdowns or damage of turbine blades. The control problem is difficult due to its “swell and shrink” effect and the dynamic characteristics. Therefore, designing a suitable controller for all power levels is extremely necessary to increase the plant safety and availability. This paper is concerned with the design of a linear parameter-varying (LPV)-based sliding mode controller for the water level control of a nuclear steam generator which has parameter-varying dynamics. The proposed controller guarantees both stability and dynamic properties in the entire operating region. The systematical design method for the controller which is automatically adjusted along the reactor power, in terms of LPV theory, is shown. Simulation results illustrate that the controller realizes the quick and accurate control in full operating range, and its performance is superior to conventional PID controllers.
